Abstract

The brush is made by taking tufts of bristles from a supply, feeding them to a mould where their anchor ends are connected to the corresp. brush body. When the tufts are inserted into openings in the injection mould they are at the same time radially compressed at least at their anchor ends which project into the mould hollow where they are secured by the surrounding injection moulding material. Sealing means are provided in the area of the openings of the mould to keep the tufts sealed in the openings at least during part of the injection moulding process which forms the brush body.
